For all Heavensward there has been a marked neglect of endgame content, in all patches. The only things that would come close would be the savage raids (where, obviously, all of the dev team's effort went -and that's really great for maybe 10% of the playerbase (and that's a wildly exaggerated guess **) who did them in their release patch) and a "casual" grind for tomestone & token equipment (which, interestingly, even casual players are able to complete in less than 2-3 weeks by skipping to the next even-numbered patch -this easily translates to skipping 4-5 months of subscription, for those interested in the "business" perspective). Besides these, there's the extreme trials and the relic, whose rewards have always been rendered obsolete on release, seemingly by design.
So, how about adding some endgame content?

** I find it most interesting that we never get even the most basic statistics, like how many characters did the savage raids in their release patch and the total number of characters in Heavensward for that patch. I guess it makes for good advertising hiding the fact that so few people care to do the content you pour your development team's efforts in; and, perhaps, a good display of self-delusion.
